Webinviscid magnetostrophic mode. Estimates suggest that planetary interiors are in magnetostrophic balance, fostering the idea that magnetostrophic flow optimizes dynamo generation. However, it is unclear if such a mono-modal theory is realistic in turbulent geophysical settings. Donna Elbert first discovered that there is a range of …

WebMay 1, 1994 · The dynamics of a buoyant parcel (or blob) of fluid released from the mushy zone on the inner core boundary (ICB) is considered. Estimates of the density defect and of the rise velocity are obtained from consideration of mass conservation and magnetostrophic force balance. WebMay 18, 2024 · We investigate the normal modes of a rapidly rotating, electrically conducting, inviscid fluid sphere in the presence of a background magnetic field. Neglecting the fast modes that are essentially slightly modified inertial waves, we focus on the slower branch of modes traditionally called magneto–Coriolis (MC) modes.

If the easy axis is in the direction, the anisotropy energy can be expressed as one of the forms: where is the … WebNov 26, 2024 · Tangentially geostrophic and tangentially magnetostrophic constraints were imposed for core flow beneath the viscous boundary layer at the core–mantle boundary …
WebIn order to obtain an improved estimate of Neptune's magnetic field and hence the size and structure of the magnetosphere, a new scaling law for planetary magnetic fields has been developed. Starting from magnetostrophic balance between the coriolis force and the j×B ponderomotive force, we have derived a scaling relation which can be used to calculate … Webthe magnitude of the MHD analogue of Lamb’s parameter is large. On a sphere, the magnetostrophic modes reside near the poles, while the other modes are equatorially confined. Magnetostrophic modes may be an ingredient in explaining the frequency drifts observed in Type I X-ray bursts from neutron stars.
